ANDREW L. WASTEL, OF SHAWANO, WISCONSIN.

MILK-COOLER.

To all whom it may concern:

Be it known that I, ANDREW L. WASTEL, a citizen of the United States,residing at Shawano, in the county of Shawano, State of Wisconsin, haveinvented certain new and useful Improvements in Milk-Coolers; and I dohereby declare the following to he a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to that class of dairy utensils employed toremove animal heat from milk and has for its object, to provide anapparatus which will effectually cool milk and at the same time strainand clear same from impurities.

Another object of the invention is the provision of a receptacle for thecooling element having a conduit communicating therewith at its base,said receptacle forming a support for the milk supply and one wall ofsaid conduit a trough for conveyingthe milk from the milk supply duringa portion of its passage to a suitable depository.

A still further object of the invention is the provision of means forsuccessively spreading the milk after it leaves the supply overconstantly increasing areas and' thus secure a more effectual coolingand aerating of same.

lVith the above and other objects in view the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully set forth and particularly claimed.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views, and in which,

Figure 1 is a side elevation of the milk cooler constructed inaccordance with the invention; Fig. 2, a top plan view of same; Fig. 3,a section on the line 33 of Fig. 2; Fig. 4c, a detail view of thestrainer, and Fig. 5, a detail view of the spreader which is associatedwith the delivery element of the milk supply and disposed within thestrainer.

Referring to the drawings 6 indicates the bottom of the device, 7 therear wall, and 8 and 9 the side walls which are of irregular formationhaving enlarged rear portions 10 and 11, and forwardly extendingdiminished portions 12 and 13 respectively; the top Specification ofLetters Patent.

edge of said diminished portions being substantially parallel to thebottom 6. Formed in the top edges of the enlarged portions 10 and 11 ofthe side walls are corresponding recesses 14 and 15 respectively havingthe converging side edges 16, 17 and 18, 19 respectively, said recessesconstituting a seat for a strainer of similar formation to behereinafter referred to. Disposed between the side walls 8 and 9 is avertical partition 20, the upper end of said vertical partitionterminating at the point of convergence of the sides of the annularrecesses 14k and 15 and short of the bottom 6 at its lower end for apurposeto be presently described. The rear wall 7 is inclined inwardlyat its upper end as at 21 to correspond with the inclined edges 16 and18 of the recesses 14 and 15. A horizontal top member 22 connects thesides 8 and 9 between the upper end of the inclined portion 21 of therear wall and the upper end of the inclined edges 16 and 18 of therecesses 14. and 15, while another member 23 connects the top of thepartition 20 with the front end of the horizontal top member 22, theportion 21 of the rear wall 11, the horizontal member 22 and the frontmember 23 constituting the top of the receptacle for the cooling elementof the device; the front wall of which is formed by the partition 20.

The front end of the conduit 25 is closed as at 26 and a dischargeelement 27 communicating with said conduit 25 is mounted in thediminished portion 12 of the side wall 8. A trough 28 is secured to thebottom 6 transversely thereof at its extreme outer end and has one ofits terminals provided with a delivery mouth. Formed in the inclinedcontinuation 21 of the rear wall 7 is a hinged door 29 through which thereceptacle for. the cooling element may be supplied. Supported upon thetop member 22 is a milk supply receptacle 30 whose bottom hassubstantially the same shape as said member 22.

A discharge element 31 is mounted in the front wall of the receptacle 30and communicates with the interior thereof. Seated in the recesses 14:and 15 so that the interior thereof will be disposed beneath thedischarge element of the milk supply receptacle is a strainer. Saidstrainer being provided with the downwardly converging side walls 32 and33 and triangular shaped end members 34 and 35. The side 33 of saidstrainer being perforated and adapted to lie V ward of the side 32 whenthe strainer is positioned in the recesses 14 and 15. Supported withinthe strainer just described by the side members 32 and 33 is a spreader36 having a spheroidal formation and provided with a pin 37 projectingupwardly from the center thereof and adapted to enter the dischargeelement 31 of the milk supply receptacle 30 so as to effectually spreadthe milk immediately same is drawn from the receptacle.

The operation of the device is as follows Assuming the receptacle 30 tobe supplied with milk and the discharge element 31 open it will beapparent that the flow of milk will be intercepted at the mouth of thedischarge element by the spreader 36 and flows over the entirespheroidal surface of said spreader during its passage into thestrainer. The milk will then pass through the perforations in the side33 of the strainer along the walls to the corrugated sheet; then alongsaid sheet into the trough 28 and then into a suitable depository by wayof the delivery spout. It will be thus obvious that during the pass ingof the milk just described the same will be spread over successivelyincreasing areas and the aeration and cooling thereof will be quicklyand effectually had.

What is claimed is:

1. A milk cooler comprising a tank for the cooling element formed of amain receptacle having a forwardly extending diminished portioncommunicating therewith at its base, the top wall of said diminishedportion being corrugated, a milk supply receptacle disposed upon the topof the main receptacle of the tank for a cooling element, a dischargeelement in communication with the interior of said milk supplyreceptacle, a strainer disposed beneath said discharge element and aspreader supported by said strainer adapted to divert the normal coursesupported by said strainer and adapted to v divert the normal course ofthe flow of milk from said discharge element into said strainer; saidstrainer having a spheroidal formation and provided centrally with anupwardly projecting pin adapted to be disposed in the discharge elementof the milk supply receptacle.

3. A milk cooler comprising a tank for a cooling element formed of amain receptacle having a forwardly diminished portion conimunicatingtherewith at its base, a milk supply receptacle disposed upon the top ofthe main portion of the tank for a cooling element, a discharge elementin communication with the interior of said milk supply receptacle, astrainer disposed beneath said discharge element, said strainer beingformed with downwardly converging sides, one of which is perforated, anda spreader supported by the converging sides of said strainer-andadapted to divert the normal course of the flow of milk from saiddischarge element into said strainer.

In testimony whereof, I afiiX my. signature, in presence of twowitnesses.
